OOMMF eXtensible Solver

The Oxs (OOMMF eXtensible Solver) is an extensible micromagnetic
computation engine capable of solving problems defined on
three-dimensional grids of rectangular cells holding three-dimensional
spins. There are two interfaces provided to Oxs: the interactive
interface
Oxsii
intended to be controlled primarily through a graphical
user interface, and the batch mode
Boxsi, which has extended
command line controls making it suitable for use in shell scripts.

Problem definition for Oxs is accomplished using input files in the
MIF 2 format.
This is an extensible format; the standard OOMMF modules are
documented below.
Files in the MIF 1.1 and
MIF 1.2 formats are also accepted. They are
passed to mifconvert for conversion to MIF 2 format
``on-the-fly.''

Note on Tk dependence: Some MIF 2 problem descriptions rely on
external image files; examples
include those using the
Oxs_ImageAtlas class, or those using the MIF 2
ReadFile command with the image
translation specification.
If the image file is not in the PPM P3 (text) format, then the
any2ppm application may be
launched to read and convert the file. Since any2ppm
requires Tk, at the
time the image file is read a valid display must be available. See the
any2ppm documentation for details.
